Find the area of the shaded region in the figure, in which two circles with centres A and B touch each other at the point C, where `AC=8cm` and `AB=3cm`

In the adjoining figure, two circles with centres P and Q intersect each other at the points B and C, ACD is a line segment . If angleARS=150^(@)andangleBQC=x^(@) , then find the value of x.

Find the area of the shaded region in the adjacent figure, where ABCD is a square of side 10cm and semicircles are drawn with each side of the square as diameter (usepi=3.14)

Find the area of the shaded region in figure, if ABCD is a square of side 7cm . And APD and BPC are semicircles. (usepi=(22)/(7))

AOB is a diamter of a circle with centreO, C is any point on the circle If AC = 6cm and BC = 8cm then AB=

Calculate the area of the designed region in figure, common between the two quadrants of the circles of radius 10cm each. (usepi=3.14)

In the adjoining figure, two tangents drawn from external point C to a circle with centre O touches the circel at the point P and Q respectively. A tangent drawn at another point R of the circle intersects CP and CQ at the points A and B respectively. If CP = 7 cm and BC =11 cm, then determine the length of BR.

Two radii OA and OB of a circle with centre O are perpendicular to each other. If two tangents are drawn at the point A and B intersect each other at the point T, prove that AB= OT and they bisect each other at a ridght angle.

In the adjoining figure, DeltaABC circumscribes a circle and touched the circle at the points P, Q, R. If AP =4 cm, BP=6cm, AC =12cm and BC =x cm, then determine the calue of x.

Find the coordinates of a point A, where AB is the diameter of a circle whose centre is (2, -3) and B is (1, 4).
